LAUNCHXL-F28027 Datasheet, PDF (6/15 Pages) Texas Instruments – LAUNCHXL-F28027 C2000 Piccolo LaunchPad

Getting Started with the LAUNCHXL-F28027
2.2 Install the Software
Once downloaded, install Code Composer Studio and the controlSUITE package.
www.ti.com
2.3 Install the Hardware
After Code Composer Studio is installed, plug the supplied USB cable into the C2000 LaunchPad board
and into an available USB port on your computer.
Windows^® will automatically detect the hardware and ask you to install software drivers. Let Windows run
a search for the drivers and automatically install them. After Windows successfully installs the drivers for
the integrated XDS100v2 emulator, your LaunchPad is now ready for use.
3 Getting Started with the LAUNCHXL-F28027
3.1 Getting Started
The first time the LAUNCHXL-F28027 is used, a demo application automatically starts when the board is
powered from a USB host. If your board does not start the demo application, try placing S1 in the following
positions and resetting the board: UP - UP - DOWN. To start the demo, connect the LAUNCHXL-F28027
with the included mini-USB cable to a free USB port. The demo application starts with the LEDs flashing
to show the device is active.
3.2 Demo Application, Internal Temperature Measurement
The LAUNCHXL-F28027 includes a pre-programmed TMS320F28027 device. When the LaunchPad is
connected via USB, the demo starts with an LED flash sequence that points toward S3. Press S3 to start
the temperature measurement mode.
A reference temperature is taken at the beginning of this mode and the LEDs of the LaunchPad are used
to display any difference between the current temperature and the reference temperature. Initially, the
LED connected to GPIO3 is lit to indicate an 8 in binary, which corresponds to the current temperature
being equal to the reference temperature. As the temperature drifts away from the reference, the
difference is displayed as a binary increment or decrement of the nibble wide LED display. For instance, if
the reference temperature was 30ºC and the current temperature is 33ºC, the LEDs would be (from left to
right) ON, OFF, ON, and ON which would be 11 in binary (33-30=3 and 11-8=3). A new reference
temperature may be set at any time by pressing S3 again.
In addition to the LED display, temperature information is also displayed on your PC through the
USB/UART connection. To view the UART information on your PC, first figure out the COM port
associated with the LaunchPad. To do this in Windows, right click on My Computer and click on
Properties. In the dialog box that appears, click on the Hardware tab and open Device Manager. Look for
an entry under Ports (COM & LPT) titled "USB Serial Port (COMX)", where X is a number. Remember this
number for when you open a serial terminal. The demo applications UART data was written and debugged
using PuTTY, and for the best user experience we recommend you use PuTTY to view the UART data.
Open your serial terminal program and open the COM port you found previously in device manager with
the following settings: 115200 Baud, 8 data bits, no parity, 1 stop bit. After opening the serial port in your
serial terminal, reset the Launchpad with the reset push button and observe the serial terminal for a
surprise.
3.3 Program and Debug the Temperature Measurement Demo Application
The project and associated source code for the C2000 Piccolo LaunchPad demo is included in the
controlSUITE software package and should automatically be found by the TI Resource Explorer in Code
Composer Studio v5. In the resource explorer, open the controlSUITE folder and then the kits tab and look
for the C2000 LaunchPad line item. Expand this item and select the LaunchPad Demo Application. Follow
the steps in the main pane of the resource explorer to import, build, debug, and run this application.
4 Hardware Configuration
The C2000 LaunchPad gives users several options as to how to configure the board.
